On the other hand, enormous benefits are achieved from recovering valuable metals and materials from such waste. Eventually, physical and chemical processing will become the most important stages
Projections indicate that indium production will reach its peak between 2025 and 2030, while the peak for photovoltaic solar panels due to indium shortages is anticipated around 2090, with an installed capacity of 1200 GW. Thus, the growth of photovoltaic capacity may lag behind actual demand.

CIGS thin-film solar technology: Understanding the basics A brief history CIGS solar panel technology can trace its origin back to 1953 when Hahn made the first CuInSe 2 (CIS) thin-film solar cell, which was nominated as a PV material in 1974 by Bell Laboratories. In that year, researchers began to test it, and by 1976 University researchers made the first p

The physical indium shortage and the dependence on an unresponsive source metal extraction rate may have ramifications for the production of large volumes of solar panels for electricity generation.
Boosting this could greatly alleviate supply pressures. Projections indicate that indium production will reach its peak between 2025 and 2030, while the peak for photovoltaic solar panels due to indium shortages is anticipated around 2090, with an installed capacity of 1200 GW. Thus, the growth of photovoltaic capacity may lag behind actual demand.
The available indium in the markets can be used for many different photovoltaic technologies, all of them important and several are mutually linked and depending on each other in combinations (Tables 1 and 2). Table 2 shows kg of indium per installed MW capacity.
The system delivers an indium supply (Figure 13 c) resulting in an installed photovoltaic collection capacity (Figure 13 d). Comparing the curves in Figure 13 b, d indicate what is going on: how the indium supply falls short of the indium demand by a huge amount. The demand for indium is satisfied until about 2024–2026.
Using the WORLD7 model, this study evaluated the sustainability of indium production and overall market supply. The model considers both mass balance and the dynamic interplay of supply–demand in determining indium prices. It is estimated that a total of 312,000 tons of indium can be extracted.
The indium price does increase enough to increase the indium recycling some, but yields limitations prevail. The result shows that the photovoltaic capacity demanded is far larger than what can be realized in reality. It appears to be not enough indium available.
